Modern

Modern is the newest constructed format. Modern was created by Wizards of the Coast in the Spring of 2011 as a response to the increasing popularity of the Legacy format, which although popular proved difficult to access due to the high price of staple cards. Modern allows cards from the 8th Edition core set and all expansions printed afterwards.
